Aim investigate the factors effecting the rate of reaction between sodium thiosulphate and hydrochloric acid


Reactions occur when particles collide the more often they collide then the faster the reaction. There is a huge difference between the rates of different reactions. Increasing the energy or frequencies of collisions between the particles can increase the rates of reactions. The rate of the reaction depends on four factors –

The surface area of the reactants that are solid – A larger surface area means that there is more chance of a collision-taking place. But as we are using both liquids in our reaction the factor does not affect us.

Concentration – Increasing the concentration of the reactants means that there will be more particles so a greater chance of a collision.

Temperature – By increasing the temperature you provide the particles with more kinetic energy, so they will move faster. This will increase the number of collisions per second so incr...
